Productive Free Agent Pickups

Manny Ramirez, C.C. Sabathia and Mark Teixeira have all produced since headlining last offseason's free agent class, but they're far from the only free agents to make meaningful contributions this season. Here are the five free agents who have been worth most this year according to FanGraphs. I've included the player's worth, as calculated by FanGraphs, his contract info and some more traditional stats:

Raul Ibanez, Phillies – He's been worth $16.1MM this year, but the Phillies are paying him just $6.5MM (plus incentives) in the first year of a deal worth $31.5MM. Ibanez has 26 homers, 75 RBI and an OPS just shy of 1.000.

C.C. Sabathia, Yankees - Sabathia has been worth $15.6MM this year, making a $14MM salary in the first year of a deal that could pay him $161MM. Despite a drop in his K-rate, Sabathia has an ERA below 4.00 in the AL East and leads the league in starts.

Mark Teixeira, Yankees – He's been worth $15.1MM so far, so he's on pace to earn the first $20MM of his $180MM deal. He's added 26 homers, 80 RBI and 56 walks to the Yankees' offense.

Bobby Abreu, Angels – He's been worth $13.8MM this year and he's making a base salary of just $5MM. What a deal for the Angels, who get an .869 OPS, nearly as many walks as strikeouts and 22 steals.

Juan Rivera, Angels - Another unheralded signing by the Angels. Rivera and Abreu have both approached Teixeira's production this year and the Yanks pay Tex more in one season than the Angels will pay Abreu and Rivera in total over the course of their current deals. Rivera makes a base salary of $3.25MM this year and will make at least $12.75MM on his new deal. He's batting .311 with 18 homers.
